BELL brand free-size protector set for elbows, knees, and wrists, ensuring safety. - Brand: BELL - Product Type: Protector Set - Contents: For elbows, knees, and wrists - Size: Free Size - Color: Black - Usage: Bicycle, skateboard, and other activities Used about 3 times when my child was 5 years old, but the child always disliked wearing them, so they were home-cleaned and stored at home. Although it varies from person to person, I think the size is suitable for children aged 3 and up to around 1st or 2nd grade elementary school. There are minor scratches, but no noticeable damage or stains. The Velcro straps fasten securely. Please consider purchasing if you understand that these are home-stored, used items.
